You're looking for an AJ Johnson (of most-recent lore)?
If you have some exra time, review this vid, closely, on " A.J. Johnson vs Florida 2012 " -- (beginning with the first 2 plays, you'll think he's in on / hitting someone on EVERY play, but keep watching) I see some very very good plays on his part, but we still lost this game even with a great LB, and for the most part AJ was 1 of 11 guys on the field (one specific good tackle which should have been penalized for hitting qb out of bounds; several times he couldn't keep up with the ball carrier; a couple of missed arm tackles; shedding blocks but unable to catch the runner; etc. -- all things we've seen from Jumper, and even JRM, to-date).
I suspect you're reaching with this possibility.
